    Is this cleanup doable on foot? I won't be able to get on the bike for awhile, but would be happy to show up and help out if hiking it works.

    Poll: are black rims overused?

    Yup. You can keep an old, well-ridden, mechanically maintained bike looking good longer with silver rims. If you're a pro and the team throws down for new rims every time you scratch some color off, then they never get worn to the point that the side is just kinda generally sand blasted, and you probably have some other color that matches your primary sponsor's graphics.

  5. Cycra put some spam in my email about their new product line. http://store.cycraracing.com/rehacorapa.html Anybody use them yet?

    why do people hate me

    I grew up in a really white town, but there were two sisters whose dad was black and whose mom was a blonde. Her maiden name went back to the founding fathers of the town in the 1800s. Every day, their awesomeness made nobody have any reason to care about their ethnicity. Just be the best person you can be, do your best at everything. The losers will fall by the wayside soon enough.
  8. Spend some time reading up on the motors. Getting the head cut correctly is key. The details are well published on the web. Pretty simple if you have the tools. Porting seems to just be extra, the head is mandatory and cleans up most of the problems to a fully acceptable level. You're right the hard part is the pipe. You'll need to mod the frame in the yoke area one way or another. I would lean toward moving the yoke up to make room for a center pipe or down to make room for the side pipe. Don't just hack on it to clear. Then you'll need to make the rest of the pipe work. I was thinking about 490 in a modern frame a lot last year. I suspect the highboy pipes would clear the rearward part of the frame (not the subframe) better on a YZ250 frame than on a 4T frame. Figure out what tank, seat and side panels to run and how to mount them. Or you'll need a custom low-boy pipe built. Which would likely be the easiest solution, but you're trusting a lot of money to a pipe builder, and hope he gets along with the stock porting or your engine builder. All very complicated to manage.

    Fully white YZ250

    Not my bike, not even my pics. Just some I found on the web and had saved on my hard drive for inspiration.

    2003 YZ160

    I have a TE610 and a YZ250. The big Husky is about 100 pounds heavier than the YZ, and you feel every pound on the trail. On the other hand, the Husky will climb up darn near anything just by pointing it uphill and opening the throttle. The YZ is going together as a WR295, which I hope will be the perfect trail bike for me at 6'4" and 250 lb. But that doesn't keep me from looking for cheap KDXs and CR125s with blown top ends on CL. If I didn't have a compulsion to build stuff, I'd probably just buy a KTM 200 XC-W. Doesn't have quite the gearing spread of the KDX, but should be a lot easier to ride on a trail than a 125 and just as light. If I was your size and planned to focus on the track, I'd definitely buy an '06 or newer YZ125.

    california plated dirtbike , dmv posible issues?

    You actually need a model year 2002 or older bike for a non-emissions bike to have a legit Cali plate. The cutoff to get a bike plated was 1/31/04, but it still had to be an '02 or older bike. That's why '03 XRRs are so cheap in Cali, and why the last few sat in dealerships unsellable for a couple years. But that still won't keep them from eventually scrubbing the reg list and sending you a GFY letter if you weren't the owner of the bike before the cutoff. I'd probably get the newest emissions-legal KTM that you like and can afford.

    california plated dirtbike , dmv posible issues?

    Officially, someone who owned a bike prior to the cutoff and maintains the tags is in good shape. But the tags won't transfer on a bike that wasn't emissions-legal when built. You might get lucky and get it through your local DMV, have it miss being caught in Sacramento, and actually get a registration. But sooner or later, they will periodically scrub the registration list, and you will get a letter in the mail notifying you that your plate is worthless and inviting you to get a green sticker. Happened to lots of people on TT, happened to a buddy of mine. That's the only reason I got a TE610 instead of an XRR. (Two years ago, when I got the bike, I lived in Cali.) Here in TX, I can plate the two-stroke if I want to.

    2006 yz250 bolts (greenish black)

    The green zinc has a chromate top coat containing hexavalent chrome. It is extremely toxic (the pollution at issue in the Erin Brockovich deal) and has been basically outlawed in the European community. Manufacturers have moved this upstream, and if you want to sell to a vehicle manufacturer that does business there, you pretty much can't use it anywhere in the products you supply. Especially for a "one spec" bike like the YZ250. It was initially a technical challenge, but technology has responded and there are now non-toxic coatings with performance on par with the old ones that contained hex chrome. Cadmium is also pretty gnarly, but it is still used in aerospace because it is supremely effective and we have this thing about airplanes falling out of the sky due to corrosion. Read up on cadmium, and you'll wash your hands after handling it. If you really want those old bolts, look for "bolt kits" from people parting older bikes on fleabay.

    Come on yamaha...

    Adam understood what I was getting at. Making a WR220 would be pointless with a five-speed. Reducing the power would be to make the necessarily narrower gears live when you fit six of them in the five-speed case. I was playing with numbers some more, and realized that a stroke slightly shorter than EG does on the 125 to make it a 155 (so we know it fits in the cases), combined with the YZ250 bore, puts you right at 200cc, just a hair under to keep it legal in under-200cc off-road classes, if any of those still exist. It ends up really dang close to where the KDX200 was for bore/stroke relationship. To do that on the 125, you'd likely need new case castings to work with the larger jug and porting layout, maybe a couple dozen new part numbers or so in total. The vast majority of the 125 bottom end could carry over, and you should be able to use a bunch of YZ250 part numbers as well, maybe even the head casting (with different machining, obviously). Most of the case machining would be the same as either the 125 or the 250, so it could probably be run on the same work holding. It would all bolt into the 125 frame just like a 125 does. And all the big tanks that are available for the 125/250 now would work. The best-handling off-road/singletrack bike in the history of the universe is within reach if Yamaha wanted to make it happen.
